The attached pictures show all four Bridgestone Potenza RE050A RFT 225/35R19 front and 255/30R19 rears after 28595 miles on a 2008 E92 335XI. The front right tire wore through on the inside shoulder and triggered the tire pressure monitor as it deflated on the highway.
All tires/wheels were removed and replaced temporarily with the winter setup of Bridgestone Blizzak LM25 225/40R18 front and 255/35R18 rear. Vehicle has not been in any collisions and there is no reason to suspect that it is out of alignment based on how it drives. The winter tires have nearly 19000 miles and appear to be wearing normally.
First pic shows all four tires arranged as they were on the car with the front right in the upper left corner of the picture. Second picture shows the tread wear on just the fronts. You can see the cracks where the front right finally leaked at the bottom of the pic. pics of the rears can be found on this thread

Is there any reason to suspect that the car is out of alignment?
Would different tires handle the aggressive stock camber, but mostly highway driving better?
Would a different tire inflation pressure wear the tires more evenly (36 psi front and 39 psi rear)?
Should I just swerve side to side on the highway like in the recon lap of F1 to get better wear?
